To all w7wm it m y OOILOWYLI erture 9 in the dial 8 is a pivot-pin 10,on Be it known that I, WILLIAM J. BUSSINGER, which is mounted, exteriorof the casing l, a a citizen of the United States, residing in thepointer 11. Secured on the pivot 10 so as to city and county ofPhiladelphia, State of Pennrotate therewith and within the casing 7 is a5 sylvania, have invented a new and useful Imgear 12, having teeth 13. Aspring 14, shown provement in Measuring Devices for Fluidas triangularin form and held in position by Pumps, of which the following is aspecilicathe engagement of one of its points between tion. lugs in thecasing, acts to hold the gear 12 My invention relates toregistering-devices, in frictional contact with the under side of 55 [Oand particularly to those used in connection the top of the casing 7.Secured to the rod with a pump for registering the number of 3 withinthe casing 7 is a cam 16, moving in strokes given the pump, and hencethe vola recess 17 within a dog 18. The dog 18 is ume of liquiddelivered. provided with a tooth 19, adapted to mesh It consists ofmeans for automatically stopwith the teeth 18 of the gear 12, and with a60 5 ping the further movement of the pump at the tail 20, moving in anotch or recess 21 in the end of a predetermined number of strokes andeasing 7.

Thefurther movement of the cam 16 carries the tooth 19 in the direction ofthe arrow, Fig. 5, until it clears the tooth 13 with which it is thenengaged and which of course has moved therewith. The dog 18 then beginsto move away from the gear 12, as shown by the arrow in Fig. 6 o1 thedrawings, and afterward in the opposite direction to the arrow shown inFig. 5 until the tooth 19 engages with the next tooth 13 of the gear 12.It will be seen that the dog 18 is free to move in a longitudinaldirection and is restrained as to its lateral movement by the engagementof its tail 20 in the recess 21 in the casing 7.

It will be seen that my device afl'ords a simple, effective, and durablemeans of predetermining the number of strokes to be given the pump andfor preventing its rotation there,- after.

It will be evident that various changes may be made by those skilled inthe art which may come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. A pump registering device comprising a pump-actuating rod, a lug onsaid rod, a pointer manually adjustable from a normal position andreturnable thereto by the movement of said rod, and a movable portioninterposed between said pointer and said rod and adapted to be moved bysaid pointer into the path of the lug on said rod, whereby the furtherrotation of said rod is prevented.

2. A pump-actuating device comprising a pump-actuating rod, a lug onsaid rod, a casing, a pointer exterior of said casing and manuallyadjustablevfrom a normal position, means within said casing whereby themovement of said rod acts to return said pointer step by step to suchnormal position, and a lever interposed between said pointer and saidrod and adapted to be moved by said pointer into the path of the lug onsaid rod, whereby the further rotation of said rod is prevented.

3. A pump registering device comprising a pump-actuating rod, a lug onsaid rod, a casing, a dial on said casing, a pointer exterior of saidcasing and manually adjustable from a normal position to a predeterminedpoint on said dial, a gear in said casing rotatable with said pointer,means movable with said rod for actuating said gear step by step, and alever pivoted exterior of said casing and having a cam-surface adaptedto be engaged by said pointer and a shoulder adapted to engage with alug on said rod, whereby through the movement of said lever caused bythe return of said pointer to its normal position, a further rotation ofsaid rod is prevented.

4:. in a pump registering device, a rotary pump-actuating rod, a cam onsaid rod, a registering device including a gear, and a bodilymovable dogactuated by said cam and adapted to move toward and away from the gearto engage successively with the teeth thereof as said rod is rotated.

5. In a pump registering device, a rotary pump-actuating rod, a cam onsaid rod, a registering device including a gear and a bodilymovable dogin which said cam is mounted and having a tooth adapted to engagesuccessively with the teeth of said gear as said rod is rotated, andmeans for properly guiding said dog.

6. In a pump registering device, a rotary pump-actuating rod, a cam onsaid rod, a registering device including a gear and a bodilymovable doginclosing said cam and having a tail engaging in a recess by which itslateral motion is restrained and a tooth adapted to engage successivelywith the teeth of said gear as said rod is rotated.

7. A pump registering device comprising a casing, a rotarypump-actuating rod passing through said casing, a lug on said rodexterior of said casing, a cam on said rod within said casing, a gearwithin said casing, a pointer exteriorof said casing and rotatable withsaid gear, a lever exterior of said casing and interposed in the path ofboth said pointer and of said lug, and a dog in said casing inclosingsaid cam and having a tooth engageable successively with the teeth ofsaid gear as said rod is rotated.
